Subscript Eight (₈) is the Unicode character at U+2088 in the Subscripts and Superscripts block. It looks like a small lowered 8 and is common in math and science text such as x₈ or C₈.
Remember
Character ₈
Unicode U+2088
Hex entity ₈
Decimal ₈
CSS escape \2088
Named entity (none)
All of these produce the same glyph: ₈. Prefer the Unicode character (or its entities) when you need that exact glyph; use <sub>8</sub> when you want semantic subscript formatting instead.

How It Works
1. Hex:U+2088 → ₈ in HTML. The browser turns it into ₈.
2. Decimal: same code point as 8328 → ₈. Same result as hex.
3. CSS: use \2088 in content (not an HTML entity). #point::after appends that ₈ after the paragraph text.
4. Semantic <sub>:x<sub>8</sub> styles digit eight as a subscript. Prefer this when you need meaning, not a specific Unicode glyph.
Pitfalls & Tips
Common mistakes when working with Subscript Eight entities.
Named?
No named entity
HTML5 does not define &sub8; or similar. Use numeric forms.
CSS vs HTML
Do not mix escapes
\2088 belongs in CSS. ₈ / ₈ belong in HTML.
₈ vs 8 vs ⁸
Different characters
₈ is U+2088; digit 8 is U+0038; superscript ⁸ is U+2078.
Glyph vs tag
Choose intentionally
Use the Unicode glyph for exact look; use <sub> for semantic subscript on any text.
Semicolon
End references
Always finish with ; — write ₈, not ₈.
Fonts
Check the glyph
Some fonts draw ₈ weakly. If appearance matters, test the font or prefer <sub>.
